Appearance-Preserving Mesh Simplification

This paper aims to simplify3D models with texture attributes.An appearance-preserving mult-i resolution simplification algorithm based on half-edge collapse operation is proposed.A new error metric based on the geometric importance and the texture-attribute importance of a half-edge are considered and used for determine the order of edge collapse in the simplification.The boundary edges and texture edges of the model are found out and marked in advance with the cost panelized by a weight during simplification. The visual experiment result shows that the proposed algorithm can get high quality approximations of original models with excellent appearance preservation even after drastic simplification procession.
